Re: [ft] Fill and stroke

[Cristian Vicol]

Thanks a lot!

The rastered glyphs look much better now. Unfortunatelly, I'm facing now a
problem which I had not previously, when working with bitmap glyphs. I need
to transform (slant) some glyphs. As long as only one glyph variant occurs
(either normal or slanted), all it's ok. But as soon I have both variants
for the same glyph and pointsize, I'm geting the SAME spans on the second
call as in the first one.

Basically I used similar code you've posted, with the difference that I'm
doing after FT_Load_Glyph

FT_Get_Glyph(face->glyph, &glyph);
if(fbSlanted)
    FT_Glyph_Set_Transform(glyph, &slantMatrix, NULL);
else
    FT_Glyph_Set_Transform(glyph, NULL, NULL);

This is called with fbSlanted TRUE or FALSE, according to input text: I'm
getting in the second call (for the same glyph/pointsize combination) the
same spans as in the first one. For all glyphs I'm using FT_Done_Glyph at
the end of the function. It seems as FreeType is doing some sort of spans
caching... What else should I reset?


Best regards,
Cristian Vicol

Hi Cristian,

As far as I know the only way to do that properly is by using freetypes
direct rendering feature. I did a small sample program to illustrate how to
do this last time the topic was on the list. Check out this link

Subject: [ft] Fill and stroke

Hello,

Is it possible with FreeType to fill and stroke a glyph in a singe raster
operation? The problem I have is that decomposed in two steps (fill and the
stroke) and then copy both images, the result does not see good. For some
fonts/glyphs the stroked glyph is smaller then the filled one (theoretically
should be bigger), for others the shape is completly different or the
difference between left offsets (bitmap.left) too big. That's why the
resulting images contain gaps between the stroked and filled glyph. Is there
a way to directly fill and stroke an outline?

Thanks!
Cristian Vicol
